It shall be the duty of every person who shall have contracted or shall be otherwise bound or legally obligated to heat or furnish heat for any building, part of any building, apartment or space occupied as an apartment house or business establishment to heat or to so furnish heat to every occupied portion of such apartment house or business establishment so that a minimum temperature of 68° F. is maintained therein at all times; provided, however, that the provisions of this section shall not apply to a business establishment or part thereof used and occupied for a trade, business or occupation where low temperatures are essential and unavoidable. With respect to the obligation or duty to furnish heat to or in an apartment house, the term "at all times" shall mean the time between the hours of 6:00 a.m. and 10:00 p.m. With respect to the obligation or duty to furnish heat to a business establishment, the term "at all times" shall mean the usual working hours of said business establishment. At no time, however, shall the temperature be permitted to fall below 55° F. in any apartment house or business establishment.
For the purposes of this article, wherever any apartment house or business establishment is heated by means of furnace, boiler or other apparatus under control of the owner, agent or lessor, said owner, agent or lessor shall have been deemed to have contracted, undertaken or bound himself to furnish heat in accordance with the provisions of this article. The term "contracted" shall be taken to mean and include an obligation arising by a written, verbal or implied contract; and the presence of heating outlets, radiators, risers or returns in any hall or apartment or subdivision of an apartment house or business establishment shall be prima facie evidence of an implied contract.
When the owner, agent or lessor of any apartment house or business establishment shall have agreed to supply refrigeration facilities, he shall and is hereby required to supply and maintain said refrigeration facilities at all times and in such manner as may be necessary for the proper and wholesome preservation of foodstuffs.
When the owner, agent or lessor of any apartment house or business establishment shall have agreed to supply hot water, sufficient water heated to at least 140° F. shall at all times be supplied.
No person shall let or occupy or suffer to be occupied separately as a dwelling any vault, cellar or underground room whatsoever, unless every part thereof shall be at least seven feet in height, measured from the floor to the ceiling thereof, and unless the same be for at least three feet of its height above the surface of the street or ground adjoining or nearest to the same, and unless there is an air space of not less than one foot below the level of the floor, and unless the same have external window openings of at least nine square feet clear at all points in elevation of the sash frame, which shall be so constructed that it or they may be opened for the purpose of ventilation.
No person, having the right or power to prevent the same, shall knowingly cause or permit any person to sleep or remain in any cellar or in any place dangerous or prejudicial to health by reason of a want of ventilation or drainage or the presence of any poisonous, noxious or offensive substance or a lack of suitable sanitary facilities.
No owner, agent, tenant or lessee of any building or any part thereof shall lease, let or hire out the same or any portion thereof to be occupied by any person or allow the same to be occupied as a dwelling or lodging place, unless such building or parts thereof, so occupied, are sufficiently lighted and ventilated and have available suitable sanitary facilities and are, in all respects, in that condition of cleanliness and wholesomeness required by this code and all applicable laws of this state.
The owner, agent or other person in charge and control of any apartment house shall provide watertight and covered receptacles for receiving garbage and other refuse matter.
